1. What is kW and kWh?

kW (kilowatt) is a unit of power, representing the rate of energy transfer. kWh (kilowatt-hour) is a unit of energy, representing the amount of energy consumed over time. This calculator converts between these related units.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( kW \) — Power in kilowatts
• \( kWh \) — Energy in kilowatt-hours
• \( Hours \) — Time period in hours

Explanation: This calculation determines the average power consumption rate when you know the total energy used over a specific time period.

3. Importance of Power Calculation

Details: Understanding power consumption rates helps in sizing electrical systems, calculating energy costs, and evaluating equipment efficiency.

4. Using the Calculator

Tips: Enter energy consumption in kWh and the time period in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), while kWh measures energy (total consumption over time).

Q2: How do I convert kW back to kWh?
A: Multiply kW by hours to get kWh (kWh = kW × Hours).

Q3: What are typical kW values for household appliances?
A: Refrigerators: 0.1-0.2 kW, AC units: 1-5 kW, Electric water heaters: 3-5 kW.

Q4: Why is my calculated kW higher than my appliance rating?
A: This could indicate the appliance was running at maximum capacity or there were multiple devices operating.

Q5: Can I use this for solar power calculations?
A: Yes, you can calculate the power output of solar panels from their energy production over time.
